| 摘 要： | A fast automatic algorithm is proposed for baseline correction of infrared (IR) spectral signals.It is devised based on iterative curve fitting where orthogonal polynomials are used.The algorithm can process both emission and absorption spectra automatically without human intervention.Orthogonal polynomials are used for curve fitting to reduce computation time.Both emission and absorption spectra are obtained and the results demonstrate the feasibility and practicability of this algorithm.
